The article appears to be mostly about projects that seem to use an "open source" development model, but are in fact proprietary software, so it doesn't seem to be about free software.
Wikipedia is no longer about free software sadly, even though that is why it exists.
When it comes to free software projects, nobody can possibly know if you are a man or a woman unless you tell them and nobody cares either - the freedom of the software is what's important.
@gugurumbe@civodul The solution is clearly not to use your real name in emails then - there is no need to manage a separate identity - you just have an email that doesn't contain your name.
@Suiseiseki@civodul “When it comes to free software projects, nobody can possibly know if you are a man or a woman unless you tell them and nobody cares either” Sometimes the “you tell them” part is triggered if you’re using your real-life name in e-mails. I happen to do that, because managing a separate identity irritates me, and some people do definitely care.
